Senators asks Google to explain delay in disclosing vulnerability

‘Google must be more forthcoming with the public and lawmakers…’

Three influential Republican U.S. senators on Thursday asked Alphabet Inc’s (GOOGL.O) Google unit to explain why it delayed disclosing vulnerabilities with its Google+ social network.

Google said this week it would shut down the consumer version of Google+ and tighten its data-sharing policies after revealing that the private profile data of at least 500,000 users may have been exposed to hundreds of external developers.

The letter from Senator John Thune, who chairs the Commerce Committee, and two other senators who chair subcommittees — Jerry Moran and Roger Wicker — asked Google to explain a reported delay in disclosing the issue.
